Service Rig (Workover Rig)

A service rig, also known as a workover rig, is a type of drilling rig that is used in the oil and gas industry to perform maintenance and repair work on existing oil and gas wells. These rigs are designed to be mobile and versatile, and they are typically used to perform a wide range of tasks, including well completion, workover, and well servicing operations.

The service rig is typically made of durable steel and other heavy-duty materials that can withstand the harsh conditions of the oil and gas industry. The rig is typically equipped with a variety of features and components that are designed to make it well-suited for a wide range of tasks. These features and components include: • The derrick: The derrick is the main structural component of the service rig and is used to support the rig's drilling equipment. It is typically made of steel and is designed to be strong and durable. • The substructure: The substructure is the base of the rig and is typically made of steel or other durable materials. It is designed to provide a stable and level platform for the rig's drilling equipment. • The power source: The power source is typically a diesel engine or electric motor that is used to power the rig's drilling equipment. It is typically designed to be efficient and reliable. • The drawworks: The drawworks is the equipment that is used to raise and lower the drilling equipment and is typically powered by the power source. • The rotary table: The rotary table is the equipment that is used to rotate the drilling equipment and is typically powered by the power source. • The mud pump: The mud pump is the equipment that is used to pump drilling fluid to the drilling equipment and is typically powered by the power source.

The engineering specifications for the service rig are: • Maximum hook load: typically up to 1,000,000 lb • Maximum drilling depth: typically up to 30,000 ft • Power source: typically diesel engine or electric motor • Mast height: typically up to 150 ft • Standard: API 4F

The service rig is designed to be both durable and efficient, with a range of features that make it well-suited for use in the oil and gas industry. It typically requires less maintenance than other types of drilling rigs, and its design allows for easy access to internal components for maintenance and repair. Its powerful hook load, drilling depth and height, as well as its versatility and durability make it a great option for maintenance and repair work on existing oil and gas wells.

Everything Planned Perfectly, Except for One Small Part... I had been transferred in specifically for my offshore drilling experience. This was the first drilling campaign the customer had ever done and I was brought in to manage the entire project - subsurface, drilling, completions, facilities and production operations. It felt ok as I had done this job many times before in many areas, but this felt special - it was new for this company, and they were nervous, which meant everything was reviewed closely. It is normal in the industry to never have enough time for planning, and this was no different, but the schedule wasn't too bad and the people I worked with were all experienced professionals so the planning went smooth.
The SCSSSV Isolation Question In some wells with surface controlled subsurface safety valves a landing nipple is used to lock and operate a wireline retrievable downhole safety valve. The wireline retrievable valve can be pulled to allow nearly full-bore access to the wellbore, however it is a question as to whether an isolation sleeve should be run or not. One of the key advantages for installing a wireline retrievable subsurface safety valve is that it can be pulled and allow larger tools to be run on wireline. However, the insert valve has to form a seal with the inside of the tubing in a safety valve landings nipple. This is achieved by running an upper and lower seal assembly made of chevron seals (or o-rings) which form a seal for the hydraulic oil in the control line to pressure up the safety valve. When wirelining, the wire will ride in a certain location (low side) and can create a groove in this sealing area. This groove can lead to the packing elements of the insert valve not forming a hydraulic seal and rendering the valve inoperable. In this particular well, there was a history of sand production, and the completion was more than 40 years old, which are both cause for concern when running slickline across a SCSSSV nipple profile. It was decided during job design to install an isolation sleeve across the landing nipple to prevent damaging the sealing profile.
Bell 206 Helicopter The Bell 206 is a single-engine, light helicopter that was first introduced in the 1960s and has been used for a variety of roles, including transportation, search and rescue, and aerial surveying. The helicopter is designed and manufactured by Bell Helicopter, a division of Textron Inc. The Bell 206 features a two-blade semi-rigid main rotor and a two-blade tail rotor. The main rotor is designed to provide lift and control, while the tail rotor is used to counter the torque produced by the main rotor and provide directional stability. The main rotor is made of aluminum, which makes it lightweight and durable. The rotor system is designed to provide a high level of performance and safety, and it is equipped with advanced vibration dampers to reduce noise and vibration.
